AVON - A head-on collision on Harrison Boulevard in Avon early Sunday morning killed two people.
The victims were identified as Joshua Deacon, 26, of Stoughton, and Tina Lachance, 49, of Brockton. The other driver, a woman in her 40s whose name was not released, suffered life-threatening injuries in the crash, David Traub, spokesman for Norfolk County District Attorney Michael Morrissey, said in a statement Sunday.
A preliminary investigation found that Deacon, a Rockland native, was driving a 2008 gray Altima west on Harrison Boulevard when he crossed the double yellow line into the eastbound lane, and struck a Hyundai traveling east, Traub said.

Lachance, a passenger in the Hyundai, was killed. The driver of the Hyundai was sent to a Boston trauma center and is undergoing treatment for life-threatening injuries, Traub said.

A passing motorist came upon the scene and called Avon police at about 12:30 a.m. Sunday, Traub said.

Avon police and fire responded, along with the Motor Vehicle Homicide unit of Morrissey's office, the State Police Crime Scene Services Section and Collision Analysis and Reconstruction Section.
